INSTRUMENT FOR HOLDING ARTIFICIAL I'IETI-I.

SPECIFICATION forming part of Letters Patent No. 745,070, dated November24, 1903. Application led March 2l, 1903.A Serial No. 148,884. (Nomodel.)

To all whom, it may concern:

Be it known that I, WILLIAM FRANK Mo- KIBBEN, a citizen of the UnitedStates, and a resident of Linneus, in the county of Linn and State ofMissouri, have invented a new and Improved Instrument for HoldingArtificial Teeth, of which the following is a full, clear, and exactdescription.

The purpose of the invention is to provide an instrument for holdingartificial teeth to be mounted, especially plate-teeth, so constructedas to firmly hold either end of a tooth while the other end is beingoperated upon and to duly accommodate the pins in the teeth whether thepins be arranged transversely or longitudinally of a tooth.

Another purpose of the invention is to construct an instru ment of thecharacter described in a very simple and economic mauparts, as will behereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, Aforming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure lis a perspective view of the instrument, illustrating a toothheld therein having its pins transversely arranged. Fig. 2 is a similarview illustrating the manner of holding a tooth in which the pins arelongitudinally arranged. Fig. 3 is a plan view of the instrument, theparts being in normal position; and Fig. 4 is a side elevation of theinstrument, the parts being in the position shownin Fig. 3.

The body A of the instrument is made of spring material, preferablyspring-steel, and comprises two parts or members 10 and l1, arranged oneover the other. These members are connected at their rear ends by ablock 12, which block may be attached to the said members 10 and 11 ormay be integral therewith, as desired. The lower member 11 is slightlylonger than the upper member 10 and is provided in its upper or innerface at its forward end with preferably two concaved surfaces 13 and 14,(best shown in Figs. 1, 2, and 4,) thus forming a lowerjaw B.

These concaved faces or surfaces 13 and 14 are adapted to accommodatethe front surfaces of plate-teeth of different formation and ofdifferent sizes. A longitudinal opening 15 is produced in the uppermember 10 of the body, extending from a point at or near its center outthrough the forward or outer end of the said member, and this opening 15is contracted at its outer end, and the inner edges of the contractedportion of the opening 15 are provided with serrations 16, asisillustrated in Figs. 1, 2, and 3, thus forming an upper jaw C, opposedto the lower jaw B.

A nose 17 constitutes an extension from the forward end of the upper jawC, and where this nose connects with the said jaw proper opposingrecesses 18 are made in the outer edges of the said member 10, whichrecesses 18 are best shown in Figs. 2 and 3.

A platetooth E is shown as being clamped inthe instrument in Figs. 1 and2; but in Figs. 3 and 4 the parts of the instrument are shown in theirnormal positions, the teeth being omitted.

In connection with the body A two slides D and D are employed. The slideD embraces or encircles both of the body members 10 and 11, and as thisslide D is carried in direction of the forward end of the instrument itbrings the jaws B and C together. The slide D is made to simply embraceor surround the upper body member 10, and its function is when slid overthe opening 15 in the said upper member to draw the serrated portions 16of the jaw C together. Each of these slides is readily removed from thebody when desirable, and when the slide D is to be used it is placed inadvance of the slide D; otherwise the slide D has a position at the rearof the slide I), as is shown in Figs. 3 and 4.

Some teeth E have pins 19 transversely arranged at one of their faces,as is shown in Fig. 1, and when such teeth are to be ground the slide Dis brought to the front and the slide D is at the rear and is inactive.The

tooth is then placed with its front face in one or the other of thecavities or recesses 13 or 14 of the lower jaw B, and the upper jaw Chas its members brought together until the nose extensions 17 from thesejaws enter the space between the pins 19, and the said pins enter therecesses 18 at the outer side edges of the said upper body member 10.Then the main slide D is carried forward until the two jaws B and C aremade to clamp the tooth firmly between them.

When pins 19 are longitudinally produced in a tooth E, as is shown inFig. 2, the nose extensions 17 from the upper jaw C are not brought intoaction, and after a tooth has been placed upon the lower jaw B the pins19L are brought between the serrated surfaces 16 of the upper jaw C andthe auxiliary slide D', which has been previously placed in advance ofthe main slide D, is then forced for- 'Ward over the upper jaw C untilthe pins 19a are firmly gripped by the serrated surfaces of the saidupper jaw. The main slide D is then carried forward, so as to cause thetwo jaws to clamp the tooth between them to a greater or less extent.

This instrument is exceedingly simple. It is durable, well adapted forthe purpose intended, and can be conveniently and expeditiouslymanipulated. It will hold a tooth, no matter how the pins are arranged,so that either end can be ground, as desired.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl l. An instrument for holding artificial teeth,comprising a body which consists of opposing spring members terminatingat their free ends in opposing jaws, one of said spring members havingauxiliary jaws, a main slide adapted to bring the main jaws in directionof each other, and an auxiliary slide for the auxiliary jaws, as setforth.

2. An instrument for holding artificial teeth, consisting of upper andlower opposing spring body members, each terminating at its free end ina jaw, one of which jaws is slotted and is provided with nose extension;and recesses at the outer edges of the niembers where the noseextensions connect with the main portion of the jaw, a main slideembracing both of the body members, and an auxiliary slide adapted totravel on the member having the divided jaw, as set forth.

3. In an instrument for holding artificial teeth, a body of springmaterial, comprising upper and lower members connected at one end andfree at the other, one member having concavities in its inner face andthe other member having a longitudinal slot therein', and serrations inthe walls of the slot at the outer end of the said member, the slottedmember being further provided with nose extensions from its outer end,having recesses in their outer side edges, a slide adapted to travelonly on the slotted member, and a main slide adapted to travel upon bothmembers of the body, as and for the purpose described.

4. An instrument for holding artificial teeth, comprising a body whichconsists of opposing springinembersterminatingat their free ends inopposing jaws, one of said members at its free end being itself slottedto form said end into a pair of auxiliary jaws opening and closing atright angles to said first-mentioned jaws of which the auxiliary pair ofjaws forms one member, and a slide for each of said jaws, said slidesbeing adapted to bring the members of their respective jaws in directionof each other, as set forth. In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses.
